IMPROVEMENT IN MACHINES FOR CROZING BARRELS.

Specification forming part of Letters Patent No. 160,966, dated March16, 1875; application filed October 3, 1874.

To all whom it may concern:

Be it known that we, SAMUEL S. STEEL and SHUBAL MUNSON, of Martin, inthe county of Ottawa and State of Ohio, have invented a certain new andImproved Machine for Orozin g Barrels, of which the following is a full,clear, and complete description, reference being had to the accompanyingdrawlugs, making part of this specification, in Which Figure 1 is a planView of the barrel-machine. Fig. 2 is an end view. Fig. 3 is a frontView. Fig. 4 is a View of the under side.

Llke letters of reference refer to like parts in the several views.

The nature of this invention relates to a barrel-machine, and the objectof which is to square or level up the ends of the barrel, chamfer, andcroze the same, thereby dispensing with the hand-tools in ordinary usefor doing the same Work.

Of the construction and operation of the aforesaid machine the followingis a detailed description: In the drawings, A represents a bench, in thetop whereof is secured the barrel-machine referred to by means of thearm B, projecting from the stem or upright 0, Fig. 3. The machineconsists of the head or wheel D. Said wheel or head is composed of ahub, E, and a flange, F. In said flange are secured two bits or blades,a, having straight cutting-edges pro ecting sufficiently far from theface of the flange to enable them to out. The blades are secured in theflange by wedges b. In the periphery of the hub is secured in a similarmanner two bits or blades, G, the cuttingedges whereof are straight andlie in the plane of the face of the hub, and projecting'therefrom farenough to permit them to out.

It will be observed that the hub is tapering from the flange downward,the purpose of which will presently be shown.

Arranged across the inside of the hub are two guides or ways, 11 H,Figs. 1 and 4. In

said ways are fitted slides I I, one on each 7 side of the center oraxis of the head. The slides are caused to tend outward toward theperiphery of the hub by a pair of semicircular springs, 0, arrangedbetween them, as shown In Fig. 4. In the outer end of each of the slidesis secured an angular cutter or croze, cl. On the shaft K is secured asmall drum, 2', Fig. 2, between the ways or guides H H. Around said drumis wound a cord or wire, 0, Fig. 4. One end of the cord is attached tothe slide I, Whereas the opposite end is secured to the slide 1. To theshaft K is also attached a lever, L, Fig. 1, whereby the crozing-slidesare operated, as will hereinafter be shown.

It will be seen that the upper part of the post G referred to is squareand made to fit and slide in a corresponding hole in the top of thebench. The lower end of the post is round and fitted in a correspondinghole in the cross-piece M under the bench. N is a cord, one end whereofis attached to the crosspiece, from which it extends through the end ofthe post to the treadle 0, where it is made fast. A sheave in the end ofthe post, also one in the side of the bench, through which the ropepasses, allow the rope to move with freedom forlifting the post, for apurpose presently shown.

The operation of the machine is as follows: The operator takes his placein front of the machine. The barrel tobeleveled, chamfered, and crozedis stood upright in the semicircle P, Fig. 4, formed in the edge of thebench. In order to do this the head or wheel is lifted up above the topof the bench by placing the foot on the treadle O. The head is thenswung around over the bench, as indicated by the dotted lines in Fig. l.The barrel being in position, the head is again brought over it, and thehub dropped down therein. The square section of the post now in the topof the bench will hold the head steadily and prevent it from turninglaterally. At this time the croze-cutters are drawn in from the face ofthe hub out of the way by means of the lever L, which is then locked bythe catch Q. The head is now made to revolve in the direction of thearrow by means of .the gearing R R, operated by the crank A. The end ofthe staves or barrel will be planed down and leveled by the cutters c inthe flange as the head revolves, during which the bevel or chamfer ofthe chime is made by the chamfercutters G G in the tapering hub of thehead. The leveling and chamfering of the edge of the barrel having beendone, the croze or groove for the heading is now out by the croze orcutters d d, which are now sprung out or allowed to be forced outward bythe springs c 0, by unlocking the lever L, whereby they were retained inthe hub while the levelingand chamfering were being. done.

The groove having been cut, the croze-cutters are now Withdrawn from thegroove by the lever L, which, on turning it in the proper direction,winds the cord 0 upon the drum i,

thereby drawing back the slides I I, and, perconsequenoe, withdraws thecroze from the groove, so that the head can be lifted from the barrel bythe treadle, to make way for its removal, to be replaced by another.
